BLOTTING BAD.,

Application filed May 16,1922. Serial No. 561,373.

To all whom t 'may concern:

Be` 1t known that l, CHARLES S. YOUNG,

a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented anew and useful Blotting Pad, of which the following 1s a specification.

This invention relates to blotting pads of the character employing' a blotting ele ment, a holder therefor and a resilient member between the holder and the blotting element, and an object of the invention is to provide a novel construction of blotting pad wherein the blotting element is selcurely held in place in the holder by the expansive force of the resilient member, thus making a very simple device. i

Another object of the invention is to provide a blotting Apad which may be applied to a surface simply by pressing it thereon; .it heingunderstood that other blotting pads must be rocked over the surface to be blotted. i

Still another object of the invention isuto provide a blotting pad which may be constructed entirely of sheet material; it be ing apparent hereinafter that in addition to a simple sheet metal boX-lile holder, all l require to carry out my invention is a blank of sheet rubber or like material, av smaller blank of less compressible material, such as cardboard, and a sheet ofblotting paper. f

The accompanying drawings illustrate the invention: l

Figure l is a perspective view of a blotting pad constructed in accordancewiththe provisions of this invention.

Fig. 2 is a longitudinal mid-section of the pad.

Fig. 3 pad.

There is provided a suitable holder, preferably of rectangular con-struction, comprising a top member fl, side flanges 5, 6 and end flanges 7, 8. V

A blotting element, such as ordinary blotting paper, is inserted between the flanges 7', 8, said blotting element comprising a longitudinally extending member 9, end

is a transverse mid-section of the flanges 10, and ears 1l connected with the.l flanges lO. The flanges 10 are/.inserted loe-` tween the end edges of ay resilient pliant body 12 and the flanges 7, 8; and the ears 1l are inserted between the topmember 4 in Figure 2. The resilient body'l2 is preferably a .sheet `of sponge rubber and lsaid member is of a lengthor width, or both length and` width, that, when placedyin positionto holdy the blotting element in the holder, it will be under compression longil tudinally or transversely or longitudinally and transversely sol as to firmly'andy releasably hold the flanges lO of the blotting element in frictional engagement ,with thek flanges. 7, 8 of the holder. lOwing to this' no other fasteningineans are required to hold lthe blot-ting' element in place inthe holder and, therefore, thevblotting element and said resilient member as clearly` shown f 9. may `bequiclrly removed and a newqone i substituted therefor, by simply compressing the body" l2 endwise .or transversely ,and withdrawingit from the holder, removing the blotter 9 and placing a blotter oflsimilar construction in position and thencompressing the body l2. endwise or transversely i and inserting it in the holder. A

Now when the resilient body l2 isv forced into the holder it will be subject vto com,-

,pression transversely and longitudinally, as n well as in diagonal directions, anddtheree fore it may be said that the` resilient body, which is ,simply cut ,from a" stock'sheetv .and which is normally of constant thiol@ ness throughout, is placed under an in- "fward radial' compression. v Thus the body tends to bulge outwardlyV at points adjacent its center. The tendency ofthe body to Vbulge in this wayl accomplishes three purposes, viZ:-A-The body. holds firmly iny i c place against movement in any directionfand against accidental dislodgment, `the blotting element is held firmly in place, and the .center ofthe yblotting element will naturally be the first to contact` 'with the `surface against which it is pressed'. ItV will be understood without the' central bulgethe edges of the resilient body .wouldprotrude slightly farther from the holderfithan would the cent-er. In fact lit is Well known that' any material cut from sheet stock when AThe bulge provided by the inward radial compression results in a void space being formed between the under surface of the top member of the holder and the top sur- `holderof box foi'm open at the bottom and face ofthe resilient body.v

To preventcollapse of the body I propose to reeiiforce the body at central points and particularly lill up the void produced by thebulge. This may be done in various ways, but inthe embodiment shown, I provide av single sheet 18 of relatively incompressible material, such as cardboard. Said.

sheet is vhereinafter termed a filler pad. ySaid'pad is of appreciably less area than theresilient body and vis preferably glued thereto.

It will be apparent now that when the device is applied to a vsurface to bepblotted, the central portion of the blotting element will be first to contact.

itself to the full area of the underlying surface to be blotted. f

lIt will be apparent now that va simple sheet metal box, a blank of sheet rubber,

'a blank of cardboard, and a blank of blot- Other'blotting pads require a rocking ino'- tioii, whereas mine is applied direct-ly and requires no rocking or tilting motion or other manipulation.

I vam aware that it is not new to employ sponge rubber above ra blotting element,

but in the prior known constructionsthe sponge rubber is not compressed into the holder so as to hold the blotting element in place asclearly set forth above.

It will be now clear that I have succeeded inproducing ablotting pad of coniparatively simple construction. Thus the blotting pad will be inexpensive to manufacture, can be sold at a profit for a comparatively small price, anda new blotter can be easily and quickly substituted for the old one.
